ERC-777/1155/721 hook without reentrancy guard
Concrete's assessment for RD-F-015 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Protocol handles ERC-20 tokens only (USDT, USDC, ETH-wrappers, WBTC). Code4rena scope explicitly covers ERC-20 variants (fee-on-transfer, rebasing, pausable) but not ERC-777/1155/721. No ERC-777 tokensReceived hook integration found. Green — not applicable to this protocol's token standard.

Methodology #
Determine whether the protocol integrates token standards with callbacks (ERC-777 tokensReceived, ERC-1155 onReceived, ERC-721 onReceived) without reentrancy guards on the affected functions.
